To @ZZ whom it may concer-n:v

Be it known that 1, BENJAMIN DUBINSKI, a citizen of the United States,residing at San Antonio, in the county of Bexar and State of Texas, haveinvented a new and useful Phonograph-Machine, of which the following isa specification.

This invention relates to sound-reproducing machines, and especially toa machine of that general class in which a plurality of records arepresented successively to a single sound-box.

The principal object of the invention is toimprove and'simplify thesound-box-traversing mechanism and insure uniformity of movement of thesame at each operation, a furthei object inthis` connection being toprovide for the movement of the sound'- box away from the recordatprecisely the same A further object of the invention is to provide forthe returning of the carriage to its initial or starting position aftereach reproducing operation and to prevent premature return movement byso constructing the mechanism that the sound-box will be moved away fromthe record .before the latter is released and allowed to' start o n itsreturn movement.

A still further obj ect of the invention is to provide for the accurateadjustment of the position ofthe sound-box with relation to the preventexcessiveJ inward movement of the sound-box and to provide means,whereby the sound-box is yieldably held andis free tomove outward to agreater or less extent during the reproducing operation.

improve .the construction ofthe record-carriers and to rovide means -forlocking the records from rongitudinal movement fon the carryingcylinders or mandrels.

With ,theseand other objects in view, as will more fully hereinafter apear, the invenin certain vnovel eatures of construc-tion and arrangementof partshereinafter fully described, illustrated inthe ac'- companyingdrawings, and particularly pointed out in thel appended claims, it beingunderstood that 'various changes in the form, proportionasize, and I`nor details of the be made without vdeparting I shaft 12, that carriesat A still further object of the invention is to j end view of the same,partly in section, on-

The present application relates to certain improvements in )soundreproducing machines ofthat general type shown in Letters Patent No.773,486, granted to me October 1 I' 25, 1904, and to which reference maybe had for specific details of construction not yshown or described inthe present application.

The ratus are supported on cluding end standards 10 and 11,'thatareprovided with bearings which are secured a said shafts extending themain shaft 12 and being connected at their opposite ends to a ring15.... .The shafts 14 are provided withreduced threaded terminalsadapted for the reception of thumbnuts y16, by which they may be Jrmlyclamped slots for the passage o said shafts in order to principalworking parts of the appa-'f a suitable frame, in-

for the reception of a one end a disk 13, to plurality of shafts 14, inparallel relation with in place, and-the rin 15 is provided with IOOpermit the convenient introduction and removal of the latter when it isdesired to change the records.

Thef several shafts are non-revoluble and barry sleeves 17, that may belocked in any* adjusted position by 'set-screws18,wthes'ei sleevesforming conical bearings which fit in f and operates on 'upper and lowersuitable o enings formed end disks -19 of the recor -carrying mandrel's20,-' thelatter being tapered inform and adapted to'receive records ofthe usual construction. The" larger end of the mandrel, or that endadjacent to the disk 13, is provided with a grooved friction-face 22,which is engaged by-a fric tion driving-disk 23 in the mannerhereinafter described for the purpose of imparting rotative movement tothe mandrel. The

.record is heldl from longitudinal movement Mounted 1n suitablebearings. in the lower portion of the frame is a horizontally-di's-`posed shaft 28, on which is ivoted thelower end of a frame 29, and saidame is provided ,at its upper end with bearings for a drlveshaft 30,which extends within the annular series of record-carrying mandrels andcar-y This shaft ries the friction driving-roller 23. n

is provided with a grooved pulley which movement may loe-'impartedsuitable driving-belt. the shaft 30 is a Worm 32, that intermeslres witha worm-wheel 33, carried by an ap-v proximately vertical shaft v34,that'is supported by brackets 35, projectingfrom the ortions` of therocking frame'29, and at thellower end'of thev shaft 34 is a worm 36,that interineshes with a Wormwheel 37 on a shaft 23,;the gearing beingso .proportioned that shaft'30 in rotating a suflicient number of timesto'eifect thereproduction of an entire record will effectja singlelrotation of the shaft 23.y

Secured tothe shaft y is adapted to engage with'the' lower yarm'41 of abell-crank leverthat is pivoted on@ stud main frame. r.,lhe upper arin43 of the bell-crank lever extends v 42, projectingv from the 'throughthe rocking frame 29 and engages a cross-bar on said frame, 'sothat whenthe shaft 23 turns the cam`40 to proper :position the arm 41 of the`bell-'crank lever the rocking frame 29 will be drawn to the rear andthe friction kdriving-pulley 23 will be forced out of engagement withthe friction-pulley of` the record-mandrel, and

when the parts are in normal position-that is to say,`vvith thesound-box out'of contact with the records and at its initial starting'-point--the projectingv active surface "of `the cam 40 will hold the arm41 of 'the bell-crank` lever in elevated position, and the rocking framewill `be in its rearmost positionwith the driving pulley 23Y inoperative;i.A Thestarting of the machine due to theinsertion of a coin or theoperation of a push-button` .or the like imparts rotative movement tothe br i 'a At the outer en of asis @bastia-that t vManet-screw' 57.

shaft 30, and j this movement transmitted through the worm-gearing to'the shaft 28 v causes cam'- 40 to move from the bell-crank lever. 41 andthe llatter in descendin allows the frame' '29 to swing forward until te driving-pulley 23 engages with the friction-pulley of the adjacentrecord-carrying mandre At the completion of each'reeording operation theprojecting surface of .thecam agrain engages the arm 41 and thev rockingame is moved back to inoperative position. The details of thismechanism, w `ch form no part of the present invention, are fullydescribed and illustrated in the Letters'y Patent hereinbefore referredto.

"At the upper front portion 'of -thernachine .is a rockshaft 45, thatfis "held in suitable bearings in the main frame` and serves as a vsuport for .the sound-box carriage 46. This sha ti is'provided with agroove 47 that extends for practically the entire length of thel shaftand is adapted for the reception of apair of antifriction-rollers 48,carried by screwsor studs-49, that extend through 'threaded openingsformed in an elongated'sleeve 50, that constitutes a base for thesound-box carriage. yTo .this shaft issecured one end. of

a helical spring 51, which is Wound around the shaft, and has its oposite endsecured to a pin or scew 52 on t el main frame, the springvtending to turn thevroclr-shaft and force the reproducing-stylus of thesoundvbox against the .record and said spring allowing the sound-box toyield to a greater or less extent during the reproducing of the record.

Depending from the sleeve 50 is an arm 5 3 that carries at its lower endan antifriction-roller 54, which when the sound box is in reproducingposition travels against a stationary rod 55,' that extends between thestandards vl0 and 11 to prevent excessive inward movement of thecarriage in case 'j cf accidental yIco breakage or imperfect a djustmentof other portions ofthe mechanism.

Secured to one end of thexshaft 45 is a col-iA llar 56, whichmay berevolubly adjusted on the shaft and locked invadjusted position bya'pendent pin 58, the lower end of which enscrew` 60, that extendsthrough a `threaded opening in a bracket 61', carried by the standard11, said screw being' proper position andthenblocked by a nut G2 andserving as a. means for limiting rotative movement ofthe rock-shaft inthe direction necessary toefl'ect engagement between thereproducing-stylus and the record.

r Pivotally connected to the upper portion of theroclring frame 29 is abar 64, the outer end of which is guided .in a suitable opening formedin the bracket 61, andin the outer face ofthe bar is a notch or recess65, through which. the pin 53 passes, rihis bar serves as This collar isprovided withv first adjusted to v vI O a means for moving the sound-boxtoward and from the record, and on reference to Fig. 2 it will be notedthat the connect on is such that when the friction-disk 23 is inoperative position the sound-box is also in operative position. If therocking frame 29 is thrown rearward to move the friction-disk 23 toinoperative osition, the movement will be transmitte through the bar 64to pin 58, and the shaft 45 will be rocked to such position as to throwthe sound box outward away from the record a position to permit thereturn of the sound-box to its initial position,this position beingdetermined by a collar 67, that is carried by the rock-shaft 45, andwhich may be firmly locked in any desired position of adjustmentbyaset-screw 68.

Mounted loosely on the shaft 28 is a grooved windin drum 70, to`whieh issecured one end o a flexible member 71 in the form of a cord or chain.This flexible-member is guided by sheaves 72 and 7 3 and at its oppositeend is secured to an eye formed in a lug 74, projecting from the endentarm`53 of the sound-box carriage. en this drum is turned in onedirection, the exible member is wound thereon and the carriage is drawnlengthwise of the record during the reproducing operation. To restorethe carriage to initial position, a Weight 75 is connected by a.suitably-guided flexible member 76 to an eye formed in a lug 77 at theopposite side of thependent arm 53, the Weight being elevated as thecarriage is drawn to the right during the reproducing operation anddescending to draw the carriage to the left at the completion of suchoperation.

The winding-drum is rovided with a recess 77, which is adaptedp toreceive a key or lug 78, projecting from the shaft 2 8, and said drum isconstantly pressed in the direction of. the key by means of a helicalcom ressionspring 80, surrounding the shaft ano bearing at one endagainst the drum and at the opposite e'nd against an adjustable collar81, carj ried by the shaft. On one of the flanges of 'the drum is a cam82, which as the drum revolves comes into engagement with a stationarycam 83, carried 'by the frame, the arrangement being such that the drumwill rotate a triiie less than a complete revolution at each operation,and this partial rotation will be suflicient to move the sound-box forthe full length of the record.

When the parts are. in normal fpositionthat is to say, are notoperating-the straight faces ofthe two cams or those faces parallel.

with the axis of the shaft 28, are in contact with each other, thestationary cam 83 acting as a stop forthe cam 82, and at this time thekey or lug 78, is not in the recess 7 7 As soon as shaft 28 commences torotate the 4key or l-ug 78 will rotate until it is. o posite the recess77,l whereupon .spring 8O force the drum in the direction ofthe key andthe latter will b`e entered in the recess, andv thereafter during theremaining portion of the rotative movement of the shaftH the drum willbe ted to the sound-boxcarriage. As the soundbox nears the end' of therecord the inclined face of the cam 82 starts to ride against theinclined-face of the cam 83,and at the completion .of the reproductionthe drum hasbeen forced outward to such an extent that'the key or lug78.isrwholly outof the recess, whereupon the Weight 75 acts to returnthe sound-box carriage to-its initial osition, and previous to 'thisoperation the rame 2,9 has een rocked to the rear and its movement hasbeen transmitted to the rock-shaft 45, raising the reproducing-stylusfrom engagement With the'record,`the cams 82 and 83 bemust -act inadvance of the cams 82 83 and o sitively move, the sound.- box outwardom the record before A the drum is released from the shaft. Thedescending movement of the weight 75 pulls the carriage to the left andat the same time rotates thewindingdrum 7() in a direction opposite tothat in which itv turned duringv the reproducing op,- eration. TheAmovement stops when vthe straight face ofthe cam 83 engages .againstthe corresponding face4 of' the cam 82.

With a device constructed accordance with this invention it isabsolutely-uniform resu s, the .sound-box being traversed to preciselyvthe same distance at each operation and returning to precisely the samepoint after neach operation, and owing to the positions of theactuatingcams it is impossible for the carriage to start on its retu'nmovement until after the stylus has been moved from engagement with therecord.

Having thus described the invention, what is claimed is combination witha sound-box carriage, of a support on which saidr carriage is slidablymounted, a Winding-drum, a flexible connection between the Winding-drumand the carriage, means for operating said drum to feed the carriage inone direction, means operable on lessthan a complete rotation of thedrum for stopping the, winding'- ,operatiom and means for restoring thecarriage to initial position.
